Elm Language

Lou Mauget Articles, Development Technologies & Tools, JavaScript, Programming, Single-Page Application Leave a Comment

This blog is about my dalliance with Elm; a purely functional, statically typed language that has type inference. It compiles to JavaScript. Functional programming is compelling, but heretofore, I’d only woven cherry-picked techniques into large object-oriented projects. In FP parlance, I’m partially applied! The times, they are a-changin’.

In this article, I’ll:
– touch on the reasoning for giving a nod to functional languages and data immutability;
– move on to Elm; a blazing-fast, statically typed, purely functional browser-side language that compiles to JavaScript and follows the principles of functional reactive programming;
– survey background items and the Elm environment;
– show a simple type-and-click application, followed by a more realistic To-do application;
– end with my impressions from functional-programming semi-outsider point-of-view.

Building a Spring Cloud Native Microservice Application on Azure, Part 1

Zach Gardner Articles, Azure, Cloud, Development Technologies & Tools, Java, Microservices, Spring Leave a Comment

The big three cloud providers (AWS, Azure, and Google Cloud, in that order) have their various strengths and areas of expertise. Most large organizations though typically pick one cloud provider for their cloud computing needs. This works well if you’re a Java shop that’s on AWS, or a Microsoft shop on Azure. But what if you’re on a large Java project in an organization that wants to use Azure? You’re in luck.

Microsoft Azure has come a long way, and is very supportive of non-Microsoft technologies. The proof though is in the pudding. Which is where this blog post comes in. I take Josh Long’s Bootiful Microservice Services, a great starting point to get a cloud native Spring microservice application up and running, and show how it can be run on Azure.

This first blog post will be all about setting up our basic microservices by walking through the various parts of Josh’s example application, with some best practices and patterns that I’ve found to be effective. Rather than a simplistic ToDo application, we’ll be basing our application off of my favorite bagel shop in New York, Original Bagel Boss in Hicksville, to manage its orders, inventory, etc. If we can run a bagel shop on a Spring application running on Azure, and keep customers happy and full of carbohydrates, then it proves out for applications of a similar size and complexity.

We’ll be staying mostly inside the familiar Java confines, then slowly start working our way out to getting our application deployed to Azure. Then we’ll start introducing additional complexity like Spring Batch jobs, a React front end, etc. A setup this complex will show that Azure is ready for prime time when it comes to running applications in production, even if they are built on non-Microsoft technologies…

April 10: Public vs. Permissioned Blockchains with Hyperledger KC

Keyhole Software Articles, Blockchain, Educational Event, Hyperledger Leave a Comment

As organizers of the new official Hyperledger Kansas City Meetup, the Keyhole Software team is excited to host the third meetup of the group on April 10, 2019.

The topic for this event is titled “Public vs. Permissioned Blockchains.”

Attend for an in-depth introduction to permissions and identity management in blockchain networks implemented with Hyperledger Fabric. We’ll introduce the pros and cons of public blockchains when compared with permissioned blockchains…

Using MongoDB and Spring Boot to Create a RESTful Web Service

Robert Rice Articles, Development Technologies & Tools, Java, Spring, Spring Boot 1 Comment

Spring Boot is a framework designed to simplify the bootstrapping and development of a new Spring application. The framework takes an opinionated approach to configuration, freeing developers from the need to define a boilerplate configuration. MongoDB is a simple set up and easy to use document database. A RESTful API is an application program interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data.

In this post, I will demonstrate the process of creating a RESTful web application with Spring Boot and MongoDB.
